This lecture from Astrobiology and Space Exploration is entitled "Pushing the Envelope for Life."
Astrobiology is a new meta-discipline which combines astronomy, biology, chemistry, philosophy, and physics in an effort to study the current state of life in the universe.
In the Stanford Astrobiology Course, lectures follow a, more or less, linear path from the Big Bang all the way to the development of complex life and, finally, space exploration. The course explains how evolutionary principles have operated at the macro, and micro, level ever since the birth of the universe we reside in today.
